hide div blocks and show expansion button on menu using cookie

I need some help implementing jQuery cookies.
I made a masonry grid in codepen where you can minimize and maximize the div blocks.
<div class="container">
<br>
<div class="row">
<div id="panel1" class="col-xs-6 col-lg-4">
<div id="title"><b>Block 1</b>
<div class="button" onclick="Close1()">-</div>
</div>
1</div>
<div id="panel2" class="col-xs-6 col-lg-4 tall">
<div id="title"><b>Block 2</b>
<div class="button" onclick="Close2()">-</div>
</div>
2</div>
<div class="col-xs-6 col-lg-4">3</div>
<div class="col-xs-6 col-lg-4 tall">4</div>
<div class="col-xs-6 col-lg-4 taller">5</div>
<div class="col-xs-6 col-lg-4">6</div>
<div class="col-xs-6 col-lg-4 tall">7</div>
<div class="col-xs-6 col-lg-4">8</div>
<div class="col-xs-6 col-lg-4">9</div>
<div class="col-xs-6 col-lg-4 taller">10</div>
</div>
</div>
<div id="footer">
<div id="icon1" class="icon" onclick="Open1()">Open 1</div>
<div id="icon2" class="icon" onclick="Open2()">Open 2</div>
</div
$('.row').masonry({
itemSelector : '.col-xs-6'
});
"use strict";
// End of what's configurable.
var clicked = null;
var pane = document.getElementById('panel1');
function Close1() {
document.getElementById("panel1").style.opacity = "0";
document.getElementById("panel1").style.display = "none";
document.getElementById("icon1").style.display = "inline-block";
}
function Open1() {
document.getElementById("panel1").style.opacity = "1";
document.getElementById("panel1").style.display = "block";
document.getElementById("icon1").style.display = "none";
}
function Close2() {
document.getElementById("panel2").style.opacity = "0";
document.getElementById("panel2").style.display = "none";
document.getElementById("icon2").style.display = "inline-block";
}
function Open2() {
document.getElementById("panel2").style.opacity = "1";
document.getElementById("panel2").style.display = "block";
document.getElementById("icon2").style.display = "none";
}

I want to be able to store these settings using jquery cookies (and/or html web storage) and after the user clicks on the button maybe add an (ajax) refresh setting to reorganize the div blocks in the masonray.
I am new to using jquery (and also cookie settings).
So i have difficulty implementing this in the code.
Any help is appreciated!
Thanks
So i made a new pen with cleaned up jquery functions and added the cookies. However the cookies work partly. I have trouble setting it for multiple divs.
What goes wrong?
if(Cookies.get("cohide")=="Enabled"){
$(".block1").addClass('minimalize');
$(".icon").addClass('inline');
}
if(Cookies.get("coshow")=="Enabled"){
$(".block1").removeClass('minimalize');
$(".icon").removeClass('inline');
}
"use strict";
// End of what's configurable.
//var clicked = null;
$('.block1').click(function(){
// remove set darkmode cookie, add lightmode cookie
Cookies.remove('coshow');
Cookies.set('cohide', 'Enabled');
$(this).addClass('minimalize');
var id1 = $(this).data().value;
//var y = document.getElementById(id1);
document.getElementById(id1).classList.add("inline");
console.log("Setted Cookie cohide");
});
$('.icon').click(function(){
Cookies.remove('cohide');
Cookies.set('coshow', 'Enabled');
$(this).removeClass('inline');
var id2 = $(this).data().value;
document.getElementById(id2).classList.remove("minimalize");
// document.getElementById(id1).style.display = "inline";
console.log("Setted Cookie coshow");
});

Resize panel to col-md-6

I'm fairly new at learning to code and I'm just playing around with something. I have a panel and I have a button above it to resize the panel.
Here is my code:
var panel = document.getElementById("panel");
function panelResize() {
if (panel.style.width >= "75%") {
panel.style.width = "50%";
} else {
panel.style.width = "75%";
}
}
<button style="margin:10px" onclick="panelResize()">button</button>
<div class="col-md-12">
<div class="col-md-6" id="panel">
<div class="panel panel-default">
<div class="panel-heading">
<p>panel heading</p>
</div>
<div class="panel-body">
<p>panel body</p>
</div>
</div>
</div>
</div>
I know this code may not be 100% so I apologize.
I would like the button to be able to increase the width of the panel to col-md-8 for example, then to return back to col-md-6 with the same button if possible.

You can do this
var panel = document.getElementById("panel");
if(panel.classList.contains('col-md-6')){
panel.classList.remove('col-md-6');
panel.classList.add('col-md-8');
} else {
panel.classList.remove('col-md-8');
panel.classList.add('col-md-6');
}

Make "continue" button appear when items selected and disappear when items unselected

My question is abou make "continue" button appear when items selected and disappear when items unselected using JavaScript.
var typpro = document.getElementsByClassName("typpro"),
continubutton = document.getElementsByClassName("continue");
var w;
for (w = 0; w < typpro.length; w++) {
typpro[w].onclick = function () {
'use strict';
this.classList.toggle("active");
if (this.classList.contains("active")) {
continubutton[0].style.height = "100px";
} else {
continubutton[0].style.height = "0px";
}
};
}
<div class=" col-md-3 col-sm-4 col-xs-6">
<div class="typpro">
<button>Volume Button</button>
</div>
</div>
<div class=" col-xs-12">
<div class="typpro">
<button style="width:98%">Other</button>
</div>
</div>
<div class=" col-xs-12">
<div class="inputpro">
<input type="text" placeholder="your Problem">
</div>
</div>
<div class=" col-xs-12">
<div class="continue">
<button>Continue</button>
</div>
</div>
</div>
</div>

So, you've got a couple of things working against you with your code as it stands.
Firstly, you need to actually define your continubutton variable, like so:
HTML
<button id="continubutton" style="display: none;">Continue</button>
JS:
var continubutton = document.getElementById('continubutton');
Then, you also need to define your typpro variable, like so:
JS:
var typpro = document.getElementsByClassName('typpro');
For what you're trying to do, I went with display: inline and display: none, instead of the height change because there would be a fair amount of additional CSS you would need to do to accomplish this. But here is the final result:
HTML:
<div class=" col-md-3 col-sm-4 col-xs-6">
<div class="typpro">
<button>Screnen</button>
</div>
</div>
<div class=" col-md-3 col-sm-4 col-xs-6">
<div class="typpro">
<button>Battery</button>
</div>
</div>
<button id="continubutton" style="display: none;">Continue</button>
</div>
And the JS:
var w;
var typpro = document.getElementsByClassName('typpro');
var continubutton = document.getElementById('continubutton');
for (w = 0; w < typpro.length; w++){
typpro[w].onclick = function () {
'use strict';
this.classList.toggle("active");
if(this.classList.contains("active")){
continubutton[0].style.display = "inline";
} else {
continubutton[0].style.display = "none";
}
};
}
EDIT: Since using height seems to be the route we need to go, here is updated code:
var w;
var typpro = document.getElementsByClassName('typpro');
var continubutton = document.getElementsByClassName('continue');
for (w = 0; w < typpro.length; w++){
typpro[w].onclick = function () {
'use strict';
this.classList.toggle("active");
if(this.classList.contains("active")){
continubutton[0].style.height = "100px";
} else {
continubutton[0].style.height = "0px";
}
};
}
<div class=" col-md-3 col-sm-4 col-xs-6">
<div class="typpro">
<button>Screnen</button>
</div>
</div>
<div class=" col-md-3 col-sm-4 col-xs-6">
<div class="typpro">
<button>Battery</button>
</div>
</div>
<div class="continue" style="height: 0;overflow:hidden;">
<button id="continubutton">Continue</button>
</div>
</div>
It's important that you set the initial height on your <div class="continue"></div> container, and that you set it to overflow: hidden; so anything that falls outside of the bounding box is hidden from view. This will allow you to animate the height so the button appears "hidden" until an option is selected.

the solution is
for (let btn of typpro) {
btn.addEventListener('click', function() {
let token = 0;
this.classList.toggle('active');
for (let i = 0; i < typpro.length; i += 1) {
if (typpro[i].classList.contains('active')) {
token += 1;
}
}
if (token > 0) {
continubutton[0].style.height = '100px';
} else {
continubutton[0].style.height = '0';
}
});
}

How can I group divs and calculate values?

I have the next structure:
<div class="container">
<div class="block">
<div class="id">1</div>
<div class="date">02/21/2015</div>
<div class="value">111</div>
</div>
<div class="block">
<div class="id">1</div>
<div class="date">02/21/2015</div>
<div class="value">222</div>
</div>
<div class="block">
<div class="id">1</div>
<div class="date">02/30/2015</div>
<div class="value">333</div>
</div>
<div class="block">
<div class="id">1</div>
<div class="date">02/30/2015</div>
<div class="value">444</div>
</div>
<div class="block">
<div class="id">2</div>
<div class="date">05/17/2015</div>
<div class="value">555</div>
</div>
</div>
I need group it and calculate values, then I need print this in my page.
Steps:
Group by ID
Group by Date (in ID)
Calculate Values (in each Date)
So, the result:
<div class="container">
<div class="block">
<div class="id">1</div>
<div class="date">02/21/2015</div>
<div class="value">333</div> <!-- 111+222 -->
</div>
<div class="block">
<div class="id">1</div>
<div class="date">02/30/2015</div>
<div class="value">777</div> <!-- 333+444 -->
</div>
<div class="block">
<div class="id">2</div>
<div class="date">05/17/2015</div>
<div class="value">555</div>
</div>
</div>
P.S. Of course, I don't need in comments. :)
Can you help me with JS/jQ code?

This is one way (demo):
var $container = $('.container'),
$blocks = $container.find('.block'),
results = {},
output = '';
$blocks.each(function () {
var $this = $(this),
id = $this.find('.id').html(),
date = $this.find('.date').html(),
value = $this.find('.value').html();
results[id] = results[id] || {};
results[id][date] = results[id][date] || 0;
results[id][date] += parseInt(value);
});
$.each(results, function (id, dates) {
$.each(dates, function (date, value) {
output += '<div class="block">' +
'<div class="id">' + id + '</div>' +
'<div class="date">' + date + '</div>' +
'<div class="value">' + value + '</div>' +
'</div>';
});
});
$container.html(output);

Add new row every set number of children

I am trying to add a new row every 2 childrens and place 2 new childrens inside a new row each time.
The starting html:
<div class="row_1"></div>
After the first run i get:
<div class="newRow">
<div class="span6" id="content"></div>
</div>
<div class="row_1"></div>
But as I keep adding I get:
<div class="newRow">
<div class="span6">...</div>
<div class="span6" id="content">...</div>
<div class="span6" id="content"></div> <== Empty extra div
</div>
<div class="newRow"></div> <== Empty extra div
<div class="row_1"></div>
Expected result would be
<div class="newRow">
<div class="span6">...</div>
<div class="span6" id="content">...</div>
</div>
<div class="newRow">
<div class="span6">...</div>
<div class="span6">...</div>
</div>
<div class="row_1"></div>
The following is the jQuery I am using
$(".nav li a").on("click", function(e) {
$('#content').removeAttr('id');
var $row = $(".row_1");
var $rowNew = $('.newRow');
if($rowNew.length < 2){
$('<div id="content" class="span6"></div>').appendTo('.newRow');
}
if ($rowNew.children().length > 2) {
$('<div class="row-fluid new"></div>').insertBefore($row);
}
else {
$('<div class="row-fluid new"></div>').insertBefore($row);
$('<div id="content" class="span6"></div>').appendTo('.newRow');
}
});

"Eventually I solved it with":
$(".nav li a").on("click", function(e) {
$('#content').removeAttr('id');
var $row = $(".span9");
var $rowNew = $('.new');
if ($rowNew.children().length > 1) {
$(".span9 div").removeClass("new");
$('<div class="row-fluid new"></div>').prependTo($row);
}
if ($(".new").length == 0) {
$('<div class="row-fluid new"></div>').prependTo($row);
$('<div id="content" class="span6"></div>').appendTo('.new');
} else {
$('<div id="content" class="span6"></div>').appendTo('.new');
}
});
